| Research Abstract |
As the self-organization phenomena in ecosystems, we have studied three phenomena : (i) bacterial colony formation, (ii) colony formation of plankton system with fish school and (iii) colony formation of infectives in the infectious disease spreading. We have proposed the stochastic models for these three self-organization processes and have analyzed the spatio-temporal pattern formation, and clarified the influence of the random fluctuation on the self-organization. Moreover, with help of the stochastic control theory, we have constructed the basis of control of the self-organization processes.
